BAR MAINTENANCE (Fig. 26)
To avoid asymmetrical wear on the bar, make sure
it is turned over periodically.
To keep the bar in perfect working order, proceed
as follows:
– grease the bearings on the nose sprocket (if
present) with the syringe;
– Clean the bar groove with the scraper (not in-
cluded);
– clean the lubrication holes;
– with a flat file, remove burr from the edges and
level off the guides.
Replace the bar whenever:
– the groove is not as deep as the height of the
drive links (which must never touch the bottom);
– the inside of the guide is worn enough to make
the chain lean to one side.
EXTRAORDINARY MAINTENANCE
All maintenance operations not foreseen in this
manual must be performed exclusively by your
dealer.
All and any operations performed in unauthorised
centres or by unqualified persons will totally inval-
idate the warranty.

– Unscrew the two nuts, remove the guard and re-
move the chain and rod.

specific liquid detergent and plug the cap.
